Continue reading to learn more about the innovative features of Dexcom G6 and how it can transform your diabetes management.

What is the Dexcom G6?

Dexcom G6 is a continuous glucose monitoring system (CGMs), a device that measures interstitial glucose readings for people with diabetes. Dexcom G6 obtains a glucose reading every 5 minutes so people with diabetes can have a constant update on what their current glucose level is and where it is trending, allowing them to respond immediately to changes for more effective and informed diabetes self-management. 

Key Features of Dexcom G6

Dexcom G6 has several features designed to provide accurate and convenient glucose readings for people with diabetes. Here are some of the key features of the Dexcom G6 CGM system:

• Customizable alerts: Users can set customizable high and low glucose alerts when glucose levels are outside their target range. These alerts can allow users to make more timely actions to manage their glucose levels effectively.
• Trend arrows: Dexcom G6 provides trend arrows that show the rate and direction of glucose change, allowing users to see how their glucose is trending overtime and make more informed treatment decisions.
• No fingerstick calibrations: Dexcom G6 does not require routine fingerstick calibrations. This features enhances the convenience and simplifies the glucose monitoring process.
• Compatibility with smart devices: Dexcom G6 is compatible with a range of smart devices, including smartphone and smartwatches. Users can easily access their glucose readings directly on their personal devices using the Dexcom app.
• Compatibility with automated insulin pump systems: Dexcom G6 is compatible with a vary of automated insulin pump systems (AIDs) which can streamline insulin delivery by automatically increasing or decreasing insulin rates depending on glucose levels. 
• Water resistant design: Dexcom G6 has a water resistant design that allows users to shower, swim, and exercise without having to worry about their sensor falling off.
• Exceptional Accuracy: Dexcom G6 has exceptional accuracy has gained FDA approval for treatment decisions without finger sticks as long as the reading displays a number and arrow and symptoms match the reading.
